18. Account executive

Account executives manage business-to-business relationships and are tasked with maintaining them. Apple has a bunch of relationships with advertisers and hardware component manufacturers, so it needs people to manage them.

14. Systems engineer

With a ton of suppliers and factories, Apple has to carefully manage logistics to make sure its products get shipped on time. Systems engineers make sure the chain isn't broken and manage Apple's risk.

11. Test engineer

Test engineers develop processes that stress test products in order to assure they meet Apple's standards for quality. They're responsible for creating a testing process that ensures every Apple device shipped is fully functional and free of defects.

9. Database administrator

Apple also has to crunch through a ton of data — whether it's usage data, serving apps through the App Store, or making sure some of its web-connected services like Siri are working. Database administrators make sure Apple's databases run quickly and don't go offline.

7. Hardware engineer

Hardware engineers are around to make sure Apple's hardware is up to snuff. Given that Apple is, at its heart, a hardware company, it makes enough sense that hardware engineers get paid slightly more than software engineers.

6. Mechanical engineer

Apple's products also face a lot of traditional mechanical problems, like dealing with heat and moving parts. Mechanical engineers make sure Apple's products don't fall apart as a result of trivial problems.

4. Product manager

Product managers make sure each product gets shipped while meeting Apple's bar for quality, and they interact with just about every part of the process. They're in touch with marketing, design, software, and hardware engineers — and everything in between.

3. Senior software engineer

Senior software engineers get paid slightly less than senior hardware engineers. At this level, you're probably working on some of Apple's most sensitive products, like maps or the iPhone operating system.

1. Industrial designer

Surprise! Steve Jobs has said time and again that Apple is a company that sits at the crossroads of design and technology. At its core, it has a bit of creative DNA (infused by music, mostly) that makes its products hum in a way companies like Google can't quite match.

Obviously the guys in charge of the overall visual appearance of a product and how it communicates visually with consumers is a key role at Apple, and a highly valuable one.
